Cause Analysis of engine burning oil

The main source of burning oil is cylinder, the cylinder contact surfaces — cylinder wall and the piston, with the gap increased due to various causes, jump up into the combustion chamber resulting in the emergence of oil burning oil, the specific reasons are the following:

First, the contact surface. Different models, different precision. Economy cars, its accuracy is slightly lower, the gap is slightly larger than some high-end car models, and thus part of the economy cars with fully synthetic motor oil are not appropriate, oil consumption will increase. In addition, each different component assembly error, leading to individual differences of the vehicle.

Second, the seal of the piston rings. The quality varies piston rings, elastic strength is also different, and up and down in the cylinder to do high reciprocating wear differences stand out, the sealing effect of different nature.

Third, with the use of time, incomplete combustion products or product coke — manganese, piston ring adhesive to lose elasticity, flat shaft friction, so that wear of the piston ring or the cylinder wall, resulting in burning oil.

Fourth, the cylinder or cylinder wall wear serious, leading to a large gap between the two, excess oil fleeing into the combustion chamber.

Fifth, engine materials and design are different, not the same requirements on the oil film.
